¿µ¹®³»¿ë¿ä¾à This standard has identified the measurement method for interference. The 1st method is to use the S/N ratio of power line signal and/or AWGN for S/N ratio of power line signal by connect with spectrum analyzer in receiving antenna. The 2nd method is performed by connect with receiver in receiving antenna.
